Marcus Rios, a backup cornerback for the Bruins, will undergo a procedure to relieve migraines and will sit out the game Saturday at Arizona State.

There was no opponent to study last week, so UCLA freshman quarterback Brett Hundley studied himself.

The off week was a chance for Hundley to catch his breath and take a look back at a season that has gone well to this point. The Bruins have a 5-2 record and Hundley has thrown 14 touchdown passes, the most by a UCLA quarterback since Drew Olson tossed 34 in 2005.

But Hundley, while taking time to rest and allow his body to heal from the beatings of half a season, pored over tape, examining his play through seven games.

"Instead of preparing for another team, I got to work on me, tune myself," Hundley said. "Usually at the start the week you're off and flying. Every week it's a new chapter, you're doing new things. The bye week, you get to relax and take a chill pill."

The only severe hiccup in Hundley's season was a 43-17 loss to California, when he had four passes intercepted.

He has passed for 1,916 yards with only three interceptions outside the California game. Hundley ranks 39th nationally with a passing efficiency of 143.48.

Yet he is far from satisfied.

"I needed to get back to basics, fundamentals, footwork, reads, all that stuff," he said. "I want to make sure that what I was doing good at the beginning of the season doesn't stop."

Void in the secondary

Marcus Rios, a backup cornerback, will undergo a sinus procedure this week and will miss Saturday's game at Arizona State.

Rios has been suffering from migraine headaches for three weeks. He has had similar sinus problems in the past.

Rios, a freshman, has played in five games as a backup to senior starters Aaron Hester and Sheldon Price, and his absence is potentially significant. Fabien Moreau, another freshman, is the only backup who has played cornerback this season. Safety Andrew Abbott has played cornerback in the past.

Line gets boost

Starting left tackle Torian White was back in full pads after undergoing a medical procedure to correct a minor heart rhythm issue last week.

White was limited to individual workouts and the stationary bicycle Tuesday. He did not participate in team drills.

"There's nothing holding me back," White said. "The doctor wanted me to rest for a few days and that sounded rational. So I was just doing a little cardio."

Coach Jim Mora expects White to be in the lineup against Arizona State.

"He should be out here, full-go, tomorrow," Mora said. "He should start and play and be fine."

Were White unable to play, the Bruins would probably shift Xavier Su'a-Filo from guard to tackle.
